Reply Partners With Mistral AI To Develop Sovereign And Enterprise-grade Artificial Intelligence Solutions

The collaboration is based on a shared vision of frontier AI, enabling organizations to deploy AI while maintaining data control, protecting sensitive information, ensuring regulatory compliance and operating on European infrastructures.

By combining Mistral AI’s high-performance models with Reply’s expertise in customizing Large Language Models (LLMs) using proprietary and domain-specific data, organizations in highly regulated sectors including public administration, defence, finance, healthcare, telecommunications, and energy can implement tailored AI solutions.

These solutions integrate seamlessly with existing systems, enhance operations, improve decision-making, and deliver measurable business value while upholding security, data sovereignty, and compliance.

A key pillar of the partnership is advanced AI model customization. Reply will become a Mistral Forge global launch partner, designing and training LLMs on specialized datasets for complex, data-intensive domains, ready for operational deployment.

Under this agreement, Reply and Mistral AI are also collaborating with the Austrian Academy of Sciences to create a custom Large Language Model for the Greek language, covering ancient, medieval, and modern texts.

The model supports researchers with advanced text search and completion and is trained on a specialized corpus including literature, digitized inscriptions, papyri, and selected modern texts.

Both companies collaborate on training and evaluation to ensure accuracy, reliability and practical relevance showcasing how sovereign AI infrastructures and advanced model customization can be applied even in highly specialized data-intensive domains.

Through this collaboration, Reply and Mistral AI offer a trusted, secure environment on European infrastructures, accelerating the adoption of advanced AI solutions while allowing organizations with strict regulatory, privacy, and data protection requirements to fully harness the potential of generative AI.

“The integration of the Mistral AI ecosystem with Reply’s experience in developing AI solutions tailored to specific business processes will enable organisations to deploy custom, secure and governable models, designed to ensure data sovereignty and data protection, that integrate seamlessly into existing operational workflows and scale reliably within enterprise architectures.” said Filippo Rizzante, CTO of Reply

Mistral AI’s Chief of Revenue Marjorie Janievicz said: We are proud to partner with Reply. Together, we will help organizations deploy AI that meets their needs for performance, control, and customisation.”
